THE BARYONIC TULLY–FISHER RELATION OF GAS-RICH GALAXIES AS A TEST OF ΛCDM AND MOND
@article{McGaugh2012THEBT, title={THE BARYONIC TULLY–FISHER RELATION OF GAS-RICH GALAXIES AS A TEST OF $\Lambda$CDM AND MOND}, author={Stacy S. McGaugh}, journal={The Astronomical Journal}, year={2012}, volume={143} }
The baryonic Tully–Fisher relation (BTFR) is an empirical relation between baryonic mass and rotation velocity in disk galaxies. It provides tests of galaxy formation models in ΛCDM and of alternative theories like modified Newtonian dynamics (MOND). Observations of gas-rich galaxies provide a measure of the slope and normalization of the BTFR that is more accurate (if less precise) than that provided by star-dominated spirals, as their masses are insensitive to the details of stellar…
